If each array entry can be stored as a word, it's pretty simple. Define a
field, VName, and store things as words in the field. VName[k] then
becomes "word k of field Vname". To store, you "put foo into word k of field
Vname" and to read you "put word k of field Vname into foo"

By using "before" and "after" you could even create a sorted array without
having to do any physical rearrangment. 

If the values don't fit well into words, you could do the same (with some
slightly greater complexity) using fields or lines in a single field as
well.
